Dan,

Great start. My two rear speakers are unfortunatly inferior to the three up front. (I also run an lfm-1 for the .1) Everytime I listen to certain sacd's with intentional discrete information on those two rear channels, i.e. Beck's "Sea Change" I am aware that they don't sound the same! I say: use five equal speakers. Note: I'm not even recommending a particular speaker. IMHO, it's more important that there is a synergy created by equality. Don't mix n' match!
